Patented Oct. 27, 1931 PATENT OFFICE CARL L. MOE, OF SALINAS, CALIFORNIA WATER CObLING SYSTEM FOR INTERNAL COMBUSTION ENGINES Application filed July 11, 1828. Serial No. 291,761. I

My invention relates to improvements in water cooling systems for internal combustion engines, and it consists in the combinations, constructions and arran ements hereinafter described and claims An object of my invention is to provide novel means for by-passing water from the engine so that it will be returned to the engine without passing through the radiator.

This by-pass 1s manually-controlled, and is designed to quickly heat the engine when starting in cold weather.

4 A further object of my invention is to provide a heating coil placed so as to warm the 16 interior of the car, this coil being in communication with the water-circulating system of the engine so that the warm water pumped from the engine will first pass through the coil before again fpassin to the engine. Valves control the ow 0 water to and from the coil, and in this way the coil can be used or not used according to the wish of the driver.

A further object of my invention is to pro- 2 vide a device of the type described which is simple in construction and which rovides means for thawing out a frozen radiator.

Other objects and advantages will appear as the specification proceeds, and the novel features will be particularly pointed out in what I hereinafter claim.

My invention is illustrated in the accompan ing drawings forming a part of this app ication, in which Figure 1 is a side elevation of an engine showing the water-circulating system ap-' plied thereto;

Figures 2 and 3 are vertical sections through a valve showing it in two positions; and

Figure 4 is a plan view of the heater.

In carrying outmy invention, I make use of an internal combustion en ine indicated generally at 1. A standard ra iator 2 is connected to the waterjacket 3 of the engine by pipes 4 and 5. A pum 6 sucks the water throu h the pipe 5 and orces it through a pipe back into the water jacket 3. The parts thus far described are standard in construction, and form no part of my invention except insofar as they cooperate with the parts now to be described.

I show in Figure 1 a by-pass pipe 8 as connecting the pipe 4 with the pipe 5. A valve 9 is placed at the juncture of the pipe 8 with the pipe 4. This valve is shown 1n detail in Figures 2and 3.

The valve 9 has a rotating member 10 which in turn has a funnel-shaped opening 11 therein. The pipe 4 connects with the inlet 12 of the valve, while the pipe 8 connects with the outlet 13. A second outlet 14 com municates with the top of the radiator2.

The valve has a handle 15 that is connected to themember 10, and this handle is oper- 65 ated by means of a rod 16 (see Figure 1) that extends from the handle to the dashboard 17. A knurled head 18 is secured to the free end of the rod 16 for permitting the operator to manipulate the handle 15.

When the handle is in the position shown in Figures 1 and 2, the valve 9 places the pipe 4 in communication with the radiator 2.

A swingingof the handle 15 into the position shown in Figure 3 rocks the member 10 75 so as to position the opening 11 to connect 1 the inlet 12 with the outlet 13. Water willnow be by-passed through the pipe 8 and will be carried back to the water jacket 3 without passing through the radiator 2.

I show a heater 19 in Figure 1 positioned so as to warm the interior of the car. A water coil 20 (see Figure 4) is disposed in the heater, and a pipe 21 (see Figure 1) connects one end of the coil with the pipe 8, while a 95 second pipe 22 connects with the other end of the coil and with the pipe 5. In case the driver wishes to have hot water flow through the coil 20, he opens valves 23 and 24 in the pipes 21 and 22 respectively, and closes valve 25. This will cause water to flow from the pipe 4 through the heating coil and back to the pipe 5.

In case the radiator freezes, as sometimes happens in the winter, the valve 26 (see Figure 1) is opened, which permits warm water to be poured into an inlet 27 where it will be brought into direct contactwith the ice and will quickly thaw it.

From the foregoing description of the various parts of the device, the operation thereof ma be readily understood.

Iii cold weather the engine can be quickly warmed by byassing the water through the pipe 8 as alrea y described. The interior of the car may also be kept warm by by-passing the warm water from the water acket through the coil 20 instead of through the radiator 2. In case of freezing, warm water may be poured into the radiator throu h the inlet 27, and this will quickly thaw t e ice contained in the bottom of the radiator and in the pipe 5.

Although I have shown and described one embodiment of my invention, it is to be understood that the same is susceptible of various changes, and I reserve the right to employ such changes as may come within the scope of the invention as claimed.

I claim:

A water-circulating system for an internal combustion engine comprising a water jacket, a radiator, a conduit for conveyin water from the jacket to the top of the ra 'ator a second conduit for conveying water from the radiator to the water jacket, a pump disposed in the second conduit, 8. by-pass communicating with said conduits, a manually-controlled valve for causing the water from the jacket to flow through the by-pass when actuated and an inlet valve in said second conduit for permitting warm water to be placed into the system, said warm water belng circulated through said jacket by said pump and being discharged into said radiator for thawing the same when frozen. or circulated through the by-pass upon actuation of the manually-controlled valve.
